I'm a beginner to Vizard. I'm trying to write code that will recognize when the user has their right arm in a right angle. I'm using vizmat.AngleBetweenVectors() to try and get the angle between the right shoulder and the right hand. To my mind, if you hold your arm at a right angle, it will read ~90 degrees.
I'm encountering two problems:
1) As I move my arm back and forth, holding it at a right angle, the degrees change.
2) It's not reading 90 degrees.
